| * | ACPI: Export events via generic netlinkZhang Rui2007-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upon ACPI events, send an "acpi_event" via Generic Netlink. This is in addition to /proc/acpi/event, which remains intact for now.

Function trace is most of the ACPI_DEBUG costs, but is not much of use for kernel ACPI debugging. Size of kernel image increased on test compile: + 48k (Full ACPI_DEBUG) + 35k (ACPI_DEBUG with function trace compiled out) Performance without function trace is also much better. Also remove ACPI_LV_DEBUG_OBJECT from default debug level as a lot vendors let Store (value, debug) in their code and this might confuse users when it pops up in syslog.

* / | x86_64: fake pxm-to-node mapping for fake numaDavid Rientjes2007-07-21
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For NUMA emulation, our SLIT should represent the true NUMA topology of the system but our proximity domain to node ID mapping needs to reflect the emulated state. When NUMA emulation has successfully setup fake nodes on the system, a new function, acpi_fake_nodes() is called. This function determines the proximity domain (_PXM) for each true node found on the system. It then finds which emulated nodes have been allocated on this true node as determined by its starting address. The node ID to PXM mapping is changed so that each fake node ID points to the PXM of the true node that it is located on. If the machine failed to register a SLIT, then we assume there is no special requirement for emulated node affinity so we use the default LOCAL_DISTANCE, which is newly exported to this code, as our measurement if the emulated nodes appear in the same PXM. Otherwise, we use REMOTE_DISTANCE. PXM_INVAL and NID_INVAL are also exported to the ACPI header file so that we can compare node_to_pxm() results in generic code (in this case, the SRAT code).

* acpi: fix potential call to a freed memory section.Aaron Durbin2007-05-17
| | | | | | | | | | | | | | | | | | | | Strip __cpuinit[data] from Node <-> PXM routines and supporting data structures. Also make pxm_to_node_map and node_to_pxm_map local to the numa acpi module. This fixes a bug triggered by the following conditions: - boot on a machine with a SLIT table defined - kernel is configured w/ CONFIG_HOTPLUG_CPU=n - cat /sys/devices/system/node/node*/distance This will cause an oops by calling into a freed memory section. In particular, on x86_64, __node_distance calls node_to_pxm().

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACPI AML supports "serialized" methods which are protected by an implicit mutex. The mutex is re-entrant for that AML thread to allow recursion. However, Linux implements notify() by creating a new AML thread. So for systems where notify() re-enters a serialized method, deadlock results. The fix is to use the Linux thread_id as the key to allowing re-entrancy, not the AML thread pointer. http://bugzilla.kernel.org/show_bug.cgi?id=5534 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

The driver will add/remove _PRT, so we can eventually remove .bind/.unbind methods. But we found that some of the _ADR-Based devices don't have _PRT, i.e. they are not managed by the new ACPI PCI bridge driver. So that .bind method is not called for some _ADR-Based devices, which leads to a failure. Now we make ACPI PCI Root Bridge Driver scan and binds all _ADR-Based devices once the driver is loaded, in the .add method of ACPI PCI Root Bridge driver. Extra code path for calling .bind/.unbind when _ADR-Based devices are hot added/removed is also added. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
